Description

Technical Field

[0001] The utility model relates to a lock, in particular to an intelligent door lock. Background Art

[0002] The existing smart door locks generally include two types. One is a smart lock that is directly wired to the household power supply. This smart lock can last forever, but due to the wired structure, it is relatively troublesome to install. The other is a smart lock with its own battery. This smart lock has a built-in rechargeable battery that can achieve self-power supply, but the battery capacity has an upper limit, so it needs to be charged regularly. However, due to the increasing number of functions of existing smart locks, compared with early smart locks (early smart locks generally only have low-energy functions such as unlocking, locking, screen lighting, and screen off), existing smart locks have added more functions, such as monitoring, especially all-weather monitoring, which consumes power particularly quickly. The existing single-battery smart door locks can no longer meet the needs of users, and directly increasing the capacity of the battery on the existing smart door locks will occupy the space for the anti-lock screw, causing it to lose the anti-lock function.

[0006] The transmission assembly includes a shell, a plurality of mounting shafts are arranged in the shell, a transmission gear set is rotatably mounted on the mounting shafts, the anti-lock shaft and the anti-lock knob are provided with a first gear part and a second gear part corresponding to the transmission gear set, and the first gear part and the second gear part are transmission-connected with the transmission gear set.

[0007] The housing is composed of a first housing and a second housing. The first housing and the second housing together form a transmission chamber, and the transmission gear set is installed in the transmission chamber.

[0008] The second housing is provided with a first through hole, and the anti-lock shaft extends from the first through hole.

[0009] The anti-locking knob comprises a knob portion and a connecting portion, the second gear portion and the connecting portion are integrally formed, and the knob portion is inserted into the connecting portion.

[0010] The first shell is provided with a second through hole, and the connecting portion extends from the second through hole.

[0011] The beneficial effects of the utility model are as follows: an unlocking mechanism is installed in the lock body of the inner door lock, a reverse locking device is arranged in the unlocking mechanism, a reverse locking shaft is installed on the reverse locking device, and the reverse locking shaft is connected with the reverse locking knob through a transmission component; a first battery compartment and a second battery compartment for placing batteries are arranged on the lock body of the inner door lock, the reverse locking knob is located outside the first battery compartment and the second battery compartment, the reverse locking knob is moved away from the conventional position through the transmission component, and sufficient space is left for the second battery compartment. At the same time, the battery capacity of the smart door lock is doubled while retaining the reverse locking function. BRIEF DESCRIPTION OF THE DRAWINGS
